TORONTO, Nov 29 (Reuters) - Canada's main stock index fell
on Tuesday as energy stocks slumped for a third straight session
due to leading oil exporters' struggle to agree on terms of a
planned production cut, while Bank of Nova Scotia
gained after a solid earnings report.

Oil prices fell more than 3 percent as Iran and Iraq
resisted pressure from Saudi Arabia to curtail their output,
complicating the efforts of the Organization of the Petroleum
Exporting Countries to reach a global output-limiting deal when
it meets on Wednesday.

The most influential weights on the index included Suncor
Energy Inc, which fell 2.5 percent to C$40.25, and
Canadian Natural Resources Ltd, down 2.7 percent to
C$41.49. The energy group retreated 2.3 percent overall.

Energy investors are also awaiting Canadian government
decisions on two major Enbridge Inc pipeline projects
that are expected on Tuesday. Shares in the company
were off 1.6 percent at C$56.50.
